TALKING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 659,738, dated October16, 1960.

Application filed February 24, 1897. Serial No, 624,823. (N model-l Toall whom it may concern:

Be it known that I, GEORGE W. GOMBER, a citizen of the United States,residing at C0- nyngham, in the county of Luzerne and State ofPennsylvania, have invented certain new and useful Improvements inTalking Machines; and I do hereby'd eclare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to talking-machines, and more particularly to thatclass thereof wherein a plurality of tablets are so grouped that any oneof said tablets may be readily placed into cooperative relationship withthe recorder or reproducer.

The object of my invention is to provide a talking-machine having amagazine designed to carry any desired number of tablets and render itpossible to bring any preferred tablet in position ready for being actedupon by the recorder or reproducer, it being understood that the saidmagazine is manually controlled through certain mechanism, the detailswhereof will be fully set forth in the following specification andillustrated in the accompanying drawings, in which-- Figure 1 representsa top plan View of my complete talking-machine. Fig. 2 is a frontelevation thereof. Fig. 3 is a section of Fig. l on line a a. Fig. 4. isa longitudinal section of the tablet spindle-shaft, showing part of thecylinder-head. Fig. 5 is a sectional view of the magazine-axle, showingthe friction clutch or brake therefor. Fig. 6 is a side view of thecontrolling mechanism for the magazine. Fig. 7 is a perspective detailof the parts shown in Fig. 6. Fig. 8 is a side view of thecarriage-elevating device, and Fig. 9 is an inner end view thereof.

In materializing my invention I provide the base 1, upon which ismounted a motorreceptacle 2, and upon said receptacle I erect thebrackets 3 and 4, designed to hold the several parts of my invention intheir respective operative positions. Upon the top of said receptacle Imount in said brackets the supporting axle or shaft 5, the free end ofwhich extends over the base 1 and is designed to hold the magazinerotatively in position. The magazine consists of the head 6, which isprovided with a series of bearing seats or sleeves 7, of any preferrednumber, each bearing-seat being arranged to extend outward sufficientlyto provide a reliable support for a head, the object of the tubularsections being to hold the plate 10 aproper distance from the head.

I provide on the inner side of the plate 10,

at points opposite the inner ends of the shafts, suitable bearing-seats12, adapted to receive a bearing-point 13, formed upon the shaft. Thefree ends of said shafts are provided with the tablet-carryingbody-section, and in order to secure the free ends of the shafts andproperly support the same while the tablet carried thereby is beingrecorded or transcribed I provide the arm 14, rigidly secured to therocking shaft 15, held by center points'in the bracket 16, which isrigidly secured to the outer end of the axle 5. cured to the sleeve 17.Said sleeve may consist of a tubular shaft of sufficient bore to snuglyreceive the axle upon which it is desired to freely rotate in eitherdirection.

I adj ustably mount in the brackets 3 4 the threaded shaft 18, the outerend of which is secured by the center point 19, mounted in the bracket3, while the inner end is provided with a suitable gear 20, designed tomesh with one of the gears 9 and adjustablyheld in position by thespring-controlled rocking finger 23. By this arrangement of the rockingarm 21 it will be observed that the gear 20 has the capacity of movingout of the path of the gears 9 when the magazine is rotated to bring Thehead 6 is sethe desired tablet into cooperation with the diaphragm. Ialso secure with the standards 3 4 the carriage shaft or track, whichconsists of a main section 24, the curved end 25, and the anchoredterminal 26. The track is rigidly held by the standards, and designed tol reciprocate upon the section 24 is the barrel 27, adapted to carry thediaphragm-arm 28 and the guiding-arm 29, having a suitablymountedthreaded block 30 for cooperation with the threaded shaft 18.

In order to rotate the magazine and automatically lock the same when thedesired tablet has been brought into alinement with the diaphragm, Iprovide the compound pawl illustrated in Fig. 7, consisting of the basemember 31, having the sleeve 32arranged to receive the rocking shaft 33and become fixedly attached thereto by means of the setscrew 34.Pivotally attached to the base member 31 is the link 35, the upper endof which is pivotally attached to the arm 36, provided with the aperture37, designed to loosely receive the axle 5 or sleeve 17, mountedthereon.

Pivotally connected to the arm 36 is the detent or pawl proper, 38,arranged to engage with one of the ratchets 39 upon the edge of theplate 10 or cooperate with said ratchets by means of the stud 40. Inorder to hold the pawl 38 in an extended position, I provide the spring41, secured to the arm 36 at one end, while the free end is so disposedthat it will engage a notch upon said pawl. The base member 31 is alsoprovided with the finger 42, adapted to elevate the free end of thedetent43 when the magazine has been brought into an adjusted position bythe operation of the rock-shaft Said detent 43 is pivoted in a suitableseat 43. The free end of the detent 43 engages one of the recesses ornotches 44, arranged upon the periphery of the plate 10, as more clearlyshown in Fig. 3. The rocking shaft 33 extends outward to the end of thebase 1 and is mounted thereon in suitable bearings 33*. The outer end ofthe shaft 33 has the upwardly-extending lever-section 45, whichterminates in a suitable handle 46. The arm 14 is provided with thelaterallycurved lip 47 and the stop 48, as fully set forth in Fig. 1.The oflice of the rocking shaft 33 is twofold, its first work being tooperate the compound pawl, and, secondly, to cause the arm 14 to moveinward, and thus force the bearing-point 49 into engagement with thebearing-seat provided in the ends of the shafts 8 when the desiredtablet is in alinement with the recorder or reproducer. As the lever 45is moved rearwardly against the stop 50, attached at a convenient pointto the casing 51, the shaft 33 is partly turned, causing the compoundpawl fixedly connected thereto and pivotally attached to the axle to somove that the pawl 38 will withdraw from engagement with the succeedingratchet, when by reversing the movement of the lever 45 until the upperend thereof engages the stop 48 upon the arm 14 the pawl will extendinto engagement with the clontiguous ratchet and rotate the magazine,and it will be ob served that at the instant said pawl is fully extendedthe arm 14 will be moved inward by the action of said lever, therebycausing the bearing-point 49 to take into the seat in the end of thetablet-spindle. The act of operating the compound pawl will lock the arm14 into engagement with the tablet-spindle. The simple act, therefore,of operating the lever 45 actuatesthe magazine and locks it in anadjusted position. The arm 14 is held normally outward by the spring 52to insure that the bearing-point 49, carried by said arm, will bewithdrawn from the path of the tablet-spindles while the magazine isbeing rotated. As a result of bringing the lever 45 forward, more orless impetus is imparted to the magazine, and in order to overcome thismovementI provide the friction contact-point 53, attached to thespring-plate 54, which in turnis secu red to the sleeve 17 by thesetscrew 55. The point 53 reaches lbosely through an aperture providedin said sleeve-into direct contact with the axle 5, and,by regulatingthe tension of the spring 54 by means of said setscrew 55the degree offriction set up between said point and axle is easily regulated, thusmaking it possible to freelyrotate the magazine in either directionwithout permitting the impetus of the movement to carry a preferredtablet-spindle past its point of cooperation with the bearing-point 49.

In order to readily elevate the arm 29 out of engagement with thethreaded shaft 18, I mount upon the outer arm, as shown in Fig. 8, thecam-lever, consisting of the sleeve 56, attached to said arm, the shaft57 in said sleeve, the crank-arm 58, attached to said shaft, and alsothe finger 59, attached to said crank,and antifriction-roller 60 uponsaid finger. V

By reference to Fig. 8 it will be seen that the outer end of the arm 29is bent downward at right angles to the body portion, and saiddownwardly-extending section is provided with a suitable aperturedesigned to receive the inner end of the sleeve 56,- it being understoodthat said inner end may be slightly reduced, if desired, in order toprevent the sleeve from havingalongitudinal movement in said aperture,though permitting the same to be easily rotated in order to loperate thefinger 59 and cause said finger to bear upon a contiguous portion of theframe, and thereby elevate the arm 29, so that the block carried therebywill be raised out of lcooperation with the threaded shaft 18.

In Fig. 13 it will be observed that the crank 58 is substantiallytriangular in outline, the shaft 57 being connected to one ngle, whilethe opposite angle 61 is suflicientlyshorteued to form the lower end ofthe crank-arm and 1 is moved toward the left, the arm 29 is droppedsufficiently to cause the threaded block to cooperate with itsshaft,when the reverse movement of said handle will move said finger tothe right until it is past the dead-center, as indicated by the centerof the shaft 57, when the point 61 will bear against the arm 29, andthus hold said arm in an elevated position, which will permit thecarriage to be freely moved to an initial point.

By means of the construction of my compound pawl for actuating themagazine the result is a differentiated movement of said magazine-thatis to say, the first movement of the shaft 33 causes the rapid extensionof the pivoted parts forming said pawl; but as the operating-lever 45 isbrought near the arm 14 such movement of the magazine, owing to thepeculiar construction of said pawl, is

.: checked until a very slow movement results at the time the desiredtablet is in position for cooperating with the bearing-point upon thearm 14. The act of rotating the shaft 33, it will be observed, causesthe upper end of the base member 31 to move out-ward, promptly actingupon the link 35; but after the pivoted point of said member and linkpasses the center or the extreme point of extension a withdrawingmovement will be imparted to said link, thus preventing further pressureof the pawl 38 upon one of the ratchets 39. The time of the passage ofthe pivoted parts past the center or extreme point of extension marksthe withdrawal of the stop 38,preventing further movement of themagazine, and at this instant the point upon the arm 14 takes into thebearing-seat provided for it in the end of one of the tablet-spindles.The outward movement of the upper end of the base 31 also elevates thefinger 42, resulting in forcing the detent 43 into registration with oneof the notches 44 at the instant said bearing-point engages the spindle,thus insuring harmonious cooperation ofthe several parts.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. In talking-machines, the combination of a rotatable magazine having asupportingaxle and means for operating the same condle-gears, the outerend of said shaft being movably mounted upon a rocking arm 21 andsuitable means to hold said arm normally downward whereby thetransmitting-gear will be permitted to move out of the path of thespindle-gears, all substantially as specified and for the purpose setforth.

3. In talking-machines, amagazine having a plurality of tablet-spindles,each spindle having an actuating-gear, in combination with adriving-shaft having a transmittinggear designed to cooperate with saidspindlegears, the end of said shaft carrying said transmitting-gearbeing mounted upon a movable arm, a spring adapted to so hold said armthat the transmitting-gear will be disposed in the path of the spindle-gears, though permitting it to have the power to move out of saidpath when it is desired to pass any one of the spindles withoutoperating it, all substantially as specified and for the purpose setforth.

4. In talking-machines, a rotatable magazine having a plurality oftablets, a transmitting-gear secured to the shaft of each tablet; adriving-gear adapted to cooperate successively with saidtransmitting-gears and means substantially as described whereby saidactuating-gear is automatically moved out of the path of thetransmitting-gear though normally disposed in said path all arranged asset forth.

In testimony whereof I affix my signature in presence of two witnesses.
